Circadian LED nightlights and chart lights bring soft, low levelillumination to any environment. Fitting into a standard junction box(single-gang, handy box, 2 inch minimum inside width) for easy installation, the MSN, MHN and MLN operate on 120-277V, delivering up to 30 lumens of illumination. The MCL Chart Light has an illuminated pushbutton switch that can be used without disturbing the patient (120V only), ideal for use in areas such as patient rooms, exam rooms, and nurse stations.
